介绍了法国BERTIN公司开发的气-雾快速冷却装置ADCO的性能、特点，及在法国GTS厂和韩国浦项POSCO厚板厂的使用效果．该冷却技术不仅优于常规正火钢板的ACC工艺，而且可实现在线直接淬火DQ工艺． The performance, characteristics and application of air-mist rapid cooling unit ADCO developed by BERTIN Company in France are introduced. The results are also used in GTS plant in France and POSCO plate factory in Pohang, South Korea. This cooling technology is not only superior to the conventional ACC process of normalized steel, but also can realize the direct on-line quenching DQ process.
